Abstract

The invention relates to the field of machining, in particular to a gear press-mounting fixture having a tooth space central position requirement. The gear press-mounting fixture solves the problem that assembly type gears are complex in press-mounting. The gear press-mounting fixture comprises a base, the base is fixed on a machine tool, a first elastic stretchy positioning rod which is symmetrical with the axis of the base is arranged on the lower portion of the outer circumferential face of the base, a second elastic stretchy positioning rod which is symmetrical with the axis of the base is arranged on the upper portion of the outer circumferential face of the base, a guide mandrel is arranged on the axis of the base, a pressure head which is located above the base is sleeved on the guide mandrel, the front end of the first elastic stretchy positioning rod is a tapered round head, and the front end of the second elastic stretchy positioning rod is a duckbilled structure. The gear press-mounting fixture is reasonable and reliable in structure and design, gears can be mounted in a pressing mode accurately, requirements for angles of tooth spaces are guaranteed, machining difficulty is lowered, input cost is low, and good economical benefits are obtained. Further, the gear press-mounting fixture has the advantages of being simple in structure, good in manufacturability, reliable, stable, and convenient and fast in operation.

Description

The gear pressing clamp
Technical field
The present invention relates to field of machining, be specially a kind of gear pressing clamp that has the teeth groove center to require.
Background technology
At present, this assembly type gear is that the cylindrical at a gear mills a kidney slot, draw singly-bound at another gear, kidney slot and singly-bound all have angular relationship with the teeth groove center line adding man-hour, with a flat key two gears are linked together, guarantee to assemble latter two workpiece raker tooth angle of the v-groove requirement.This structure is more employing in the engine design at home generally, and as Shanghai Diesel Engine Plant, all there are similar products in Dalian Diesel Engine Plant and Wuxi Diesel Engine Plant etc.This structural design requires not strict to pressing clamp, as long as two gears are fitted in together, but Gear Processing is complicated.
Summary of the invention
The present invention exists processing than complicated problems in order to solve when existing assembly type gear press-fits, and a kind of gear pressing clamp is provided.
The present invention adopts following technical scheme to realize: the gear pressing clamp, comprise the base that is fixed on the lathe, the bottom of base outer circumference surface is provided with the elastic telescopic backstay I with base axle center symmetry, the top of base outer circumference surface is provided with the elastic telescopic backstay II with base axle center symmetry, the place, axle center of base is provided with the guiding axle, be installed with the pressure head that is positioned at the base top on the guiding axle, the front end of elastic telescopic backstay I is the taper round end, and the front end of elastic telescopic backstay II is the duckbill structure.
Before press-fiting, earlier gear position is fixed with elastic telescopic backstay I; Then another gear is placed on the position before press-fiting, II accurately locatees with the elastic telescopic backstay; Subsequently pressure head is placed on another gear, with forcing press two gears is press-fited and be fitted in together.The elastic telescopic backstay II of duckbill structure makes gear teeth portion and its be in always and contacts in the location that being symmetrical arranged of elastic telescopic backstay I and elastic telescopic backstay II is in order to prevent that workpiece from press-fiting middle rotation.Exist processing than complicated problems when having overcome existing assembly type gear and press-fiting.
Reasonable in design of the present invention is reliable, has realized accurately press-fiting of gear, has guaranteed the angle requirement of teeth groove; And the difficulty of processing reduction, input cost is lower, has favorable economic benefit.Has advantage simple in structure, that processing technology good, reliability is stable and convenient to operation.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1-base, 2-elastic telescopic backstay I, 3-elastic telescopic backstay II, the 4-axle that leads, 5-pressure head.
The specific embodiment
The gear pressing clamp, comprise the base 1 that is fixed on the lathe, the bottom of base 1 outer circumference surface is provided with the elastic telescopic backstay I2 with base 1 axle center symmetry, the top of base 1 outer circumference surface is provided with the elastic telescopic backstay II3 with base 1 axle center symmetry, the place, axle center of base 1 is provided with guiding axle 4, be installed with the pressure head 5 that is positioned at base 1 top on the guiding axle 4, the front end of elastic telescopic backstay I2 is the taper round end, and the front end of elastic telescopic backstay II3 is the duckbill structure.
